Classification of Computers (original) (raw)
When computers first came out, they were as big as building rooms and had comparatively modest processing rates. Microprocessor technology led to a significant reduction in computer size and an increase in processing performance. Computers can be made in many different shapes and sizes with different processing powers, depending on their intended uses. In generally the computer systems can be classified on the following basis: Classifications of Computers System:-A. According to Size. B. According to Purposes. C. According to technology. A) According to Size Based on their outward size, internal capabilities, and external purposes, computers are divided into four classes. 1. Supercomputer 2. Mainframe computer 3. Minicomputer 4. Microcomputer SUPER COMPUTER The super computers are the most high performing system. A computer that performs better than a general-purpose computer is called a supercomputer. Supercomputer performance is usually measured in FLOPS (floating-point operations per second) instead of MIPS (million instructions per second). These are specially made to perform multi-specific tasks. Therefore, many CPUs work in parallel order on these supercomputers. This function of a Supercomputer is called Multiprocessing or Parallel Processing. The first supercomputer was created in the 1960s for the American Department of Defence (USA). All of the world's fastest 500 supercomputers run Linux-based operating systems. Supercomputers actually play an important role in the field of computation, and are used for intensive computation tasks in various fields. There are two broad categories of supercomputers: general purpose supercomputers and special purpose supercomputers. General purpose supercomputers can be further divided into three subcategories: 1) Vector processing supercomputers. 2) Tightly connected cluster computers. 3) Commodity computers. Supercomputers designed specifically to accomplish a specific task or objective are referred to as special purpose computers for the opposite reason. Application-Specific Integrated Circuits (ASICs) are usually used by them, and they provide higher performance.

General-Purpose computers -those built for a great variety of processing jobs. Simply by using a general purpose computer and different software, various tasks can be accomplished, including writing and editing (word processing), manipulating facts in a data base, tracking manufacturing inventory, making scientific calculations, or even controlling organization's security system, electricity consumption, and building temperature. General purpose computers are designed to perform a wide variety of functions and operations. You will probably use this type of computer reading this article and I am using a general purpose computer typing this article in some software (MS Word). A general purpose computer is able to perform a wide variety of operations because it can store and execute different programs in its internal storage. Unfortunately, having this ability is often achieved at the expense of speed and efficiency. In most situations, however, you will find that having this flexibility makes this compromise a most acceptable one.
The Evaluation Process of Supercomputer
This report takes a keen look at the evaluation of super computer technology with a view to encouraging computer and learns the history of their profession and its technologies. I do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.” This report therefore emphasizes the need to study history of the computer because a proper study and understanding of the evolution of computers, some general information about high-performance computer architectures and the various processors and communication networks employed in these systems is given in order to better appreciate the systems information given in this report. Undoubtedly help to greatly improve on computer technologies.
Advanced Computer Architecture
The first computer like machine was the Mark I developed by a team from IBM and Harvard University. It used mechanical telephone relays to store information and it processed data entered on punch cards. This machine was not a true computer since it could not make decisions.
Study of Supercomputer's Architecture, Application and Its Future Use
2013
Generally there is only one mother super computer in each country and there are many sub super computers attached to the mother super computer. It helps in increasing the speed of calculation and can quickly perform the complex tasks as given by users because of its high processing speed and the parallel computing skills. The super computers are very useful in terms of scientific research and industrial field. It also takes the level of national scientific development to a certain extent of highness. In this paper the architecture and application of the super computer has been discussed and future development of the super computer has been proposed.
Categories and Generations of Computers
2015
This scientific article speaks about generations of computers, PC history, saving data, Von Neumann architecture, input/output peripherals, software instructions, programs, mainframe, minicomputers, microcomputers, supercomputers, libraries and operating systems, computer networks and Internet, introduction to the world of computers, evolution of computer systems, from the literature specialized in computer science. Computers are divided into: mechanical computers-water and gas meters, electromechanical computers-electricity meters, electronic computers (I generation of computers, II generation of computers, III generation of computers, IV generation of computers), optical computers and biological computers. After the highest prevalence, electronic computers are divided into: analogue-electronic computers, digital electronic-computers and hybrid electronic computers.
